.PP
The function \fBitem_count\fR returns the count of items in \fImenu\fR.
.SH RETURN VALUE
The function \fBmenu_items\fR returns a pointer (which may be \fBNULL\fR).
It does not set \fBerrno\fP.
.PP
The function \fBitem_count\fR returns \fBERR\fR (the general \fBcurses\fR error
return value) if its \fImenu\fP parameter is \fBNULL\fP.
.PP
